No Thread Weld Studs (NT) are plain-body ARC weld fasteners designed for applications that require a permanent welded attachment point without threaded engagement. The smooth shank configuration allows the stud to function as a locating pin, mounting post, spacer, or attachment member within welded assemblies.
Commonly used in fabrication, equipment manufacturing, industrial machinery, and production assemblies, these no-thread weld studs are installed using the ARC stud welding process and can be manufactured in carbon steel or stainless steel to customer-specified dimensions.
No Thread Weld Studs are engineered for applications requiring a non-threaded attachment member capable of transmitting positioning, shear, retention, or bearing loads through a full-fusion ARC stud weld.
The absence of external threads preserves the full nominal shank diameter throughout the stud body, eliminating thread root reductions and maintaining maximum available cross-sectional area above the weld interface.
The plain-body configuration promotes consistent load transfer through the stud section, making it suitable for applications involving bearing contact, component location, fixture retention, and mechanical positioning.
Designed for use with diameter-specific ferrules that control arc containment, molten metal displacement, and weld flash formation while supporting repeatable weld geometry during installation.
Compatible with designated chuck, grip, and foot assemblies that maintain stud perpendicularity, plunge depth, and lift parameters required for consistent ARC stud welding performance.
Stud diameter, body length, projection requirements, material grade, and weld-end configuration can be manufactured to customer drawings and dimensional specifications for specialized assembly applications.
Available in carbon steel and stainless steel alloys to satisfy application requirements involving structural performance, fabrication compatibility, environmental exposure, and corrosion resistance.
No Thread Weld Studs can be manufactured for positioning, retention, support, and mounting applications where threaded engagement is unnecessary. Provide your dimensional requirements and application details for a custom-engineered solution.
